This development is the latest in a series of differences between the Infosys board and founders on matters of governance.The rift between software major Infosys’ current board and its founders has surfaced again, with NR Narayana Murthy writing a mail recently to the board, where the key demand from Murthy was to make the investigation reports public, two persons familiar with the development told ET NOW business news channel.

The reports refer to internal investigations constituted by Infosys after two whistleblower complaints to market regulator Sebi alleged improprieties in its $200 million acquisition of Panaya, questions over the severance payout made to former CFO Rajiv Bansal and alleged excessive expenses incurred by its current CEO Vishal Sikka in Palo Alto.

Infosys had published the conclusion & summary finding statement of the investigation by Gibson Dunn & Crutcher in June, where the law firm said it found no evidence to support the whistleblowers allegations on conflict of interest in the Panaya case, its valuation or CEO expense.

Narayana Murthy wants the board to make the entire report and its scope public, to enhance transparency and accountability. While Murthy did not offer comments to a list of queries sent by ET NOW seeking confirmation, Infosys said in an email response, "The company does not plan to make the report public."

The two sources ET NOW spoke to had seen the mail sent by Murthy. "It was a pretty detailed mail, where he sought details on the scope of the report and clear disclosure that there was no financial benefit or ties between investors of Panaya and executives at Infosys who had managed the acquisition then. He also sought details of a mail trail of former chief compliance officer David Kennedy where he had written about former CFO Rajiv Bansal’s severance payout," one of the persons said.

The other person said Infosys board was reluctant to make the report public as this would violate client confidentiality agreements between Panaya’s investors and their Limited Partners. Panaya is Infosys' second biggest acquisition till date.

This development is the latest in a series of differences between the Infosys board and founders on matters of governance. The Infosys board recently elevated independent director Ravi Venkatesan to co-chairman and also set up a committee of directors who would held the CEO in strategy and also engage with shareholders.
